Hard to say if you can teach epiphanies. But I can share what just clicked for me one day when I was in grade school:
An emotional reaction to a situation depends on the situation and the interpretation of that situation.
You can rarely control the situation but you can take ownership of the interpretation.
If something unfair happens I can be sad about the injustice I've experience or I can hope that one day that person will learn to be fairer. I remember reflecting on things that made me sad and trying to figure out a point of view that wouldn't make me sad. I realized that often times I was sad for myself and that felt pretty selfish which really ran counter to my fledgling moral system.
Even when it was someone else in pain, I was seeing that often I was sadder about my disempowerment than their pain.
